Description

この構成では、図６（ａ）に示すように、レンズ側端子面１２２よりも高さを低くした端子隣接部１３５ａによってカメラ側端子ピン２２２が電気絶縁部１３５に乗り上げることはほとんど阻止され、接触不良が回避される。このため、レンズ側端子面１２２に図５（ａ）に示したような余裕幅Ａを設ける必要がない。したがって、レンズ側端子部１２０の端子配置方向での大きさを、図５（ａ）に示した構成に比べて小さくすることができる。例えば、端子配列方向における電気絶縁部１３５の幅を、カメラ側端子ピン２２２の外径よりもかなり小さくすることができる。 In this configuration, as shown in FIG. 6A , the camera-side terminal pin 222 is almost prevented from riding on the electrical insulating portion 135 by the terminal adjacent portion 135 a whose height is lower than the lens-side terminal surface 122. Defects are avoided. For this reason, it is not necessary to provide the margin width A as shown in FIG. Therefore, the size of the lens side terminal portion 120 in the terminal arrangement direction can be reduced as compared with the configuration shown in FIG. For example, the width of the electrical insulating portion 135 in the terminal arrangement direction can be made considerably smaller than the outer diameter of the camera side terminal pin 222.
